b. 2.6 x10^-3
c. 4.0 x10^3
d. 2.6x10^3 seconds

The value of the period of the wave is the reciprocal of its frequency in hertz or 1/s. From the given above,
                        T = 1 / f = 1 / (2.3 x 10^3 1/s) = 4.35 x 10^-4 s
Thus, the answer is letter A. 

f = frequency of the  buzzing sound of honey bees = 2.3 x 10² Hertz

T = Time period of a bee's wing beat

The Time period of bee's wing beat is inversely related to frequency and is given as

T = 1/f

inserting the values

T = 1/(2.3 x 10²)

T = 4.35 x 10⁻³ seconds

hence the correct choice is

a. 4.3x10^-3
